Saudi security agents have arrested 28 men for allegedly planning to attack holy sites around Mecca and Medina during the recently finished hajj pilgrimage, the kingdom's Interior Ministry said Sunday. The announcement comes two days after the ministry said it detained an unknown number of men after security forces foiled a plot to carry out a terror attack on holy sites outside Mecca. But Sunday's statement did not say whether the two were arrests were related.

According to the AP, the ministry said 27 of the men were Saudi nationals and one was a foreign resident. "Thanks to God, the security forces managed to detain members of the deviated group who have links with elements outside (the kingdom) while planning to carry out criminal acts inside," a statement by the Interior Ministry statement said.
